Abstract: A device for reducing drips from a nozzle comprising a valve body comprising a frusto-conical outer surface, a first aperture that receives the stem of a movable valve closure mechanism, and one or more additional apertures that allow fluids to flow through the valve body when the valve is opened. In an exemplary embodiment of the invention, the spring biased movable valve closure mechanism comprises a stem extending in the direction of the longitudinal axis of the valve body, a frusto-conical valve head that maintains a fluid barrier seal with the outer surface, and a spring that biases the valve closure mechanism in the direction of the longitudinal axis of the valve body.
